Nightcrawler: AI pentesting agent on a smartphone

What's this about?

An open-source agent that runs security scans of networks you're authorized to test — entirely locally, from a phone.

What exactly is "pentesting"?

Penetration testing: probing your own systems the way an attacker would, to find holes before someone hostile does. Legitimate when authorized; the interesting part here is packaging it as a local agent on commodity hardware.

  1. On-device appeal: security tooling that phones home is its own risk; local-only agents dodge that.
  2. The obvious dual-use worry: the same convenience serves unauthorized scanning.
  3. Skepticism about depth — a phone agent runs scans, but real pentesting is the judgment layer above the scans.
